Why does Windows still store the OA3xOriginalProductKey in plain text in the registry?

I’ve been digging through the registry and noticed yet again that the OA3xOriginalProductKey sits there in nearly plain sight under HKLM. Considering how much Microsoft touts security improvements across Windows versions, why hasn’t this changed? This feels like an attack surface that really shouldn’t exist, given how valuable product keys can be for both licensing and piracy reasons.

I’m aware of the “it’s needed for recovery/redeployment” argument, but surely there’s a more secure way than just leaving the key in the open, retrievable by anyone with local access? Is there some technical limitation I’m missing, or is this more about legacy support for OEMs? Has anyone seen any official response or roadmap about encrypting or otherwise locking down product key storage on future Windows versions? Why isn’t Windows tying the licensing token to TPM or Secure Boot elements?

Curious if others find this odd, and if anyone knows of workarounds (besides obfuscating/hiding the registry entries manually, which breaks stuff). Isn’t it time for Microsoft to rethink this approach?

Yeah, it really does seem like a holdover from older Windows deployment practices, especially for big OEMs. Microsoft leans on activation servers and digital licenses these days, but that plain text key is still there for legacy scenarios. I haven’t seen anything from Microsoft about changing it, though. Maybe with Windows 12 or if more features get pushed to integrate with the TPM, we’ll see some movement. It’s frustrating, but for now, the best defense is physical security and tight user permissions.

Honestly, it’s pretty ironic-Windows can lock down BitLocker keys like Fort Knox, but leaves the product key sitting out with a neon “Hello, pirates!” sign. At this point, unless Microsoft changes their activation plumbing (which, let’s face it, they haven’t rushed to do in decades), best bet is just to limit who gets admin access and pretend we’re not all constantly side-eyeing that registry entry. Maybe next Windows version, right?

It’s wild that there isn’t even an event log entry or audit trail when that key gets accessed, considering how sensitive it is. At the very least, Microsoft could add an access alert or give system admins a policy option to further restrict or mask it. Guess we’ll just have to keep hoping for better controls in a future update.
